Conscious governments in the developing countries try to keep abreast of developments, by offering better services to their citizens; one of the important services is to preserve the natural water resources.

Implementation of constructed wetlands part of sustainable water resource management and ecosystem is a new approach for water treatment and biological disposal of contaminants, therefore families can contribute to these treatments through the use this system in their houses.

In order to meet the demand of daily water consumption by separating greywater from wastewater and for its reuse after treatment constructed wetland systems are one of the successful ecological treatments to reduce the concentration of pollutants in greywater. In view of the acute water crisis supply in Iraq, the best solution found for covering the daily consumption of householders is to apply the constructed wetland for treatment of greywater. The implementation of green roofs technique is one of the best ways to intercept rainwater. Especially in Iraq, where this technique can be used to provide thermal insulation, and an appropriate environment, to use the roofs for sleeping at night in the summer season.
